Data Packets into 3 parts 1.Header - Sender/Receiver's IP address,Protocol,Packet no 2.Payload - Data 3.Trailer - Data to show end of packet,Error correction
Bandwidth - The speed of transmission of Data Packets,it is measured by bitrate(no of bits/sec) and latency(time taken to receive data)
Recipient - Receiver/Responder Sender - Requester
2.Protocol
Each Device has it's own unique address called IP Address.
- set of rules used to communicate between machines. IP/TCP - IP routes information to proper address/TCP facilitates transmission of Data Packets. HTTP/HTTPS(GET/POST) - Facilitates communication between Web Browser and Web Server , HTTPS data packets are encrypted using SSL(Secure socket layer) or TSL(Transport security layer) certificates!
